PEA-SHELLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 466,021, dated December 29, 1891.

Application tiled May 26, 1891.

To @ZZ whom t may concern:

Be it known that We, GEORGE H. OLNEY,of Brooklyn, in the county of Kings and State of New York, and JOHN W. HARBIN, of the city and county of New York and State of New York, have invented a new and useful Improvement in Pea-Shelling Machines, of which the following is a specification.

Our invention relates to an improvement in pea-shelling machines in which provision is made fordistributin g the peas in the pod regularly and in proper direction to the shellingrollers, the entire mechanism for feeding, shelling, and separating the peas and pods being' of simple construction and arrangement, with the end in view of adapting it to general use.

A practical embodiment of our invention is represented in the accompanying drawings, in which- Figure 1 is a View of the machine in vertical section taken longitudinally of the rollers and drive-shaft and showing several of the parts in elevation, the section being taken upon the line o: a: of Fig. 2. Fig. 2 is a view in vertical transverse section, and Fig. 3 is a view in detail, in end elevation, of one set of the adjustable boxes in which the shellingrollers are journaled.

A represents a suitable casing, in the bot-- tom of which there is located a removable drawer a for the reception of the shelled peas. The top of the casing is provided with an opening over which the hopper B is located, the said hopper terminating at its upper end in an outwardly-flaring mouth b. The lower portion of the hopper is provided with a se:A ries of partitions b h2, of different heights, the higherand lower partitions being located alternately within the hopper. The space between two consecutive partitions b b2 is intended to be somewhat greaterthan the width of the largest pea-pod, but not as wide as the length of the pod, the intention being to cause the pods to assume a position transversely across the machine as they fall into the spaces between the partitions h b2. The object of forming the alternate partitions higher than those adjacent to them is to prevent the formation of a bridge of the pods and the consequent clogging lof the feed.

Serial No. 394,144. (No model.)

The unbroken surface formed by the higher and lower partitions effectually overcomes such tendency to bridge and keeps the feed continuous. Immediately beneath the lower end of the hopper B the reciprocating distributer is located. lt consists of an oblong frame subdivided by cross-partitions c, the distances between two consecutive partitions c being somewhat less than the spacesl between the partitions b b2 at the ybase of the hopper and corresponding thereto. The eX- tent to which the distances between the partitions c are lessened is not intended tovbe sufficient to form a ledge on which a pod could lodge, but is intended rather for the purposeof arranging the pods in more perfeet alignment transverse to the machine.

The reciprocating distributer O is given an endwise movement in one direction at predetermined intervals by means of one or more cams d on the side of a drive-wheel D,which, as the wheel is rotated, come in contact with the end of a stud or pin c,{ixed to the end of the distributer and extending through the vwall of the casing into the path of t-he said cam or cams d. The said distributer is given its movement in the opposite direction by means of a spring E, secured at one end to a fixed support e and at its opposite end to a supporte', secured to the distributer-frame.

The drive-wheel D is mounted upon a shaft F, journaled in suitable bearings in the casing, the said shaft F being provided with a crank f or a drive-pulley f', or both, so that the shelling-machine may be operated either by hand or by a suitable source of power not shown, as may be desired.

From a point beneath the distributor() the chute G .extends downwardly in a slanting direction to the shelling-rollers. The chute G is divided into lsubdivisions by means of partitions g, the distances between two consecutive partitions gbeirig such as to confine a pea-pod to a direction lengthwise of the chute G and at the same time allow it sufticient play to travel freely down the chute. The distances between the partitions g are preferably made somewhat less than the dis- IOO will be brought nearerandnearer to a direction transverse to the machine in order to insure their being fed endwise between the shellingrollers. The spaces between the partitions g correspond with the spaces between the partitions c in the distributer, and the throw of the distributer is such that when moved in one direction under the tension of the spring E it will close the passages between the distributer and the chute and open the passages between it and the hopper; but when thrown in the opposite direction under the impulse of a cam (l, it will allow the pods to fall from the spaces in the distributer into the several subdivisions of the chute and close the entrance of the pods from the hopper to the distributer.

At the lower end of the chute G the shelling-rollers H and Il are located. The rollers H and lvl are provided with longitudinal corrugations 7L on their perpheries and are intended to rest when not separated by the introduction of the pea-pods between them with their corrugated faces in contact. The pea-pods as they leave the subdivisions of the chute G are directed between the two rollers, and the rotary movement of the rollers will tend to draw the pods between them and will thereby press them open, throwing out the peas on the side of the rollers on which the pods enter and carrying the pods themselves through and discharging them upon the opposite side. The rollers H H are preferably journaled in sliding boxes h h2 and the rollers may be held from separation beyond the desired limit by means of set-screws I, inserted in the ends of the frames t', in which the boxes are located, and having a bearing against the boxes of the hopperroller.

An opening a is provided in the front of the casing in front of the shelling-rollers, and a guard K extends obliquely upward from the bottom of the opening a to a point in proximity to the meeting' faces of the rollers and in close proximityto the lower roller for the purpose et directing the pods after the peas have been extracted therefrom along through the opening a' outside of the casing.

The roller II is provided with a pulley L, ixed on its shaft in position to receive a driving-belt Zirom the drive-wheel D. The drivewheel D and pulley L may be connected by a belt Z, or they may be of the well-known sprocket type and connected by an ordinary sprocket-chain. rlhe opposite end of the shaft ot' the roller H is provided with a gear-wheel M, iixed thereon, which is adapted to interniesh with a corresponding gear-wheel M', fixed on the shaft of the upper roller H, so as to give the rollers a movement simultaneously in opposite directions. The gears M M may have long teeth sufficient to account for any adjustment of the rollers away from each other which may be found desirable in practice.

. That we claim is- 1. The combination, with a feed-hopper, a chute having subdivisions for directing the pods lengthwise to the shelling mechanism, and means for extracting the peas from the pods, of a reciprocating distributer located between the hopper and the subdivided chute, the said distributer being provided with a series of subdivisions corresponding to the subdivisions of the chute and adapted to open and close the passage-ways4 between its subdivisions and those of the chute to distribute the pea-pods therein, substantially as set forth.

2. The combination, with a hopper provided at its lower end with partitions extending to different heights, a chute provided with several subdivisions, and means for shelling the peas as they leave'the chute, of a reciprocating distributer provided with subdivisions corresponding to those at the base of the hopper and the chute, the said reciprocating distributer being located between the hopper and the chute and adapted to close the passage-ways between it and the hopper and sim ultaneousl y open the passage-ways between it and the chute, substantially as set forth.

3. The combination, with the subdivided hopper, the subdivided chute, and the reciprocating distributer located intermediate ot' the hopper and chute, the subdivisions in the distributer being somewhat narrower than those in the hopper and the subdivisions of the chute being somewhat narrower than those in the distributer, of shelling mechanism in position to receive the pods from the chute and means for operating the distributer and shelling mechanism, substantially as set forth.

4. The combination, with a subdivided hopper, the subdivided chute having a downward inclination, and a reciprocating distributer for distributing the pods'thcrein, of corrugated-faced shelling-rollers in position to receive the pods from the chute, means for determining the separation of the rollers, a guard for conducting the pods from the side of the rollers opposite that to which the peas are fed, and a receptacle for the peas as they fall from the side of the rollers on which the peas in the pod are fed, substantially as set forth.

`5. The combination, with the subdivided hopper, the chute, the distributer intermediate of the hopper and chute, and the rotary shelling-rollers, of a drive-wheel connected with the rollers for operating them, said drivewheel being provided upon its face with one or more cams and the distributer being provided with .an operating stud or pin in position to engage the cam on the drive-wheel, substantially :is set forth.
